The above-mentioned studies of childhood overhearers of a language give reason to believe that remnants of phonology in perception may be available, perhaps at an unconscious level, in our population of adoptees, who were monolingual speakers of Korean before adoption. We tested this possibility with a phonetic discrimination task3 involving a three-way VOT contrast in Korean and compared the results of the adoptees with those of native Koreans and of monolingual French speakers.
